Comparison of Different Methods to Achieve the Weight for Groundwater Vulnerability Assessment of Nitrate Pollution
摘要
Abstract
Based on three different methods to ascertain the weights of some groundwater vulnerability assessment of nitrate pollution,three different weights were acquired and the groundwater vulnerability of nitrate pollution in Huanghuaihai plain in Henan province was evaluated,and the three different methods and results were compared with each other.The results showed that the method of expert experience was easy to manipulate,but subjective factor always resulted in overemphasis of some factors.Subjective factors could be avoided by the principal component analysis,but it was hard to select some factors so that the result could not be controlled.Correlation analysis was used to evaluate the relationship between the selected factors and the content of the groundwater nitrate,able to eliminate subjective factors,so the result was reasonable for the studied area.关键词
